Mario Lopez talks baby (and future babies)

Mario Lopez and wife Courtney Mazza are getting ready for baby No. 2, but expanding their family even further is already on the hunky star's mind.

"We're on board [to the idea of having more kids]," Lopez told us yesterday while promoting National Iced Tea Day for Lipton.

Just like they did with their 2-year-old daughter, Gia, Lopez and Mazza did not find out the sex this time around, which he said is a truly "exciting surprise."

"I can't believe [welcoming the baby is] just around the corner, the home stretch," said Lopez, 39.

"It feels awesome," he added of becoming a proud papa for the second time.

For now, the family is getting ready to celebrate Father's Day this Sunday -- with a mariachi brunch, Mexican food and friends -- and lots of outdoor summertime activities.

"I'm a big advocate of health and fitness," Lopez said. "In the summer, I'm always running around, swimming a lot, surfing, hiking and doing stuff outside with the family."
